Show HN: Zen Mode – a global focus mode for macOS

Author here, I made this macOS tool "Zen Mode" to provide a global focus mode that works across apps. There are plenty of things approaching this (HazeOver, Stage Manager, built-in full-screen mode, etc.) but nothing quite like I imagined. The basic idea is to have a shortcut to bring the current window front and center and fade everything else to black like a spotlight, and when you're done, the window returns home, and the lights come back up. A simple solution with about 250 lines of Hammerspoon Lua, built with Fable, though with many iterations to get the UX right. Happy to answer any questions or hear any feedback.

I wish I could have a tool like this that would focus multiple windows from different apps this way. My workflow just requires different apps at the same time.

Would be great, and it's technically possible to spotlight multiple windows in this setup. But I wonder about the mechanics of picking the right apps. One way is to use named sets, e.g. dev=(iTerm2, Safari), each with their own shortcut. Another is to to focus one window and then use Cmd+Tab as an picker to choose which app to add next. I guess it depends on whether the arrangement is changing or relatively stable.
